Letters Patent No. 95,910, dated Octoberq 19, 1869.

IMPROVEMENT IN WATER-WHEELS.

l w- The Schedule referred to in these Letters Patent and making vpart of the same.

To all whom fit may concern Be it. known that I, JOHN J KIMBALL, of N aperville, in the county ofDu Page, and State of Illinois, have invented a new and useful Improvement in \Vaand I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled 'in the art to make and use Ythe same, reference being had to the accompanying drawing, forming part of this specification.

The object of this invention is to provide an improved construction of water-wheels, calculated to utilize the power of the water to a greater extent than is done bythewheels how in use, and,also, for more ready'and economical application of the said wheels to the fiume or penstock.

Figure l represents a vertical sectional elevation of my improved wheel, and

Figure 2 represents a horizontal section of the same.

Similar letters of Areference indicate corresponding parts.

A represents the case or curb, having a closed top and vertical spaces B in the sides, forming chutes for conducting water to the buckets.

C represents "an extension of the case below the rvheel intothe tail water, to produce a draught or suc`v tion on the discharging water.

The gate is composed of the ring D, having vertical wedge-shaped extensions E, fitted to -the interior of The case A, and inclined on the inside from front to rear, toward the buckets of thewheel.

By turning this ringl I), the gates are moved to open orclose thepassages B, and theyhave the effect to guide the Water to the buckets in the most direct course, whether wholly or partly opened, so that the water acts with equal advantage, irrespective of the Volume.

The wheel is composed of rims G and G', open at the top, arms H, projecting downward from thev rim G', and buckets I, attached to the said arms, and to the rim G.

By reason of the opening through the top, the upward'pressnre of the water is avoided, and the force of the water in the vertical direction is so nearly balanced as to allow the wheel to bearewith its own weight on the step.

The said buckets are so shaped in thel vertical parts as to receive the direct impelling force of' the water, and in the angular parts below a reacting effect is produced, which is aidedby the-suction produced by the extension of the part C of` the case below, into the tail water. l

This wheel may be readily set into position in the bottom of a ume or penstoek, by making a hole therein, for the reception of the extension C, to allow vthe flanges I to rest on the floor around the hole,

where they'may be secured by bolting or otherwise, as preferred.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- I. 'lhe combination, with the case A, having the chutes B, of the ring D, and vertical wedge-shaped projections E, 'substantially as specified.

2. The combination, with the wheel, composed ofthe rings G G', vertical arms H,and buckets I, having vertical and inclined faces, of the tubularextension C ofthe case, substantially asspeciied.
